Explanation:

    C    : Classification system:

            L  - linear ordering of the winners according to the total number of points obtained

            A  - three groups of the prize winners and one group of those who obtained the honourable mentions - the minima for each group were calculated in respect to the theoretically possible highest score

            R  - as A, but the minima were calculated in respect to the best score reached at a given Olympiad

            R3 - as A, but the minima were calculated in respect to the mean value of the three best scores reached at a given Olympiad

    T    : number of the Theoretical problems

    E    : number of the Experimental problems

    MT   : possible Maximum scores for each of  the Theoretical problems

    ME   : possible Maximum scores for each of the Experimental problems

    M    : theoretically possible Maximum total score at a given Olympiad

    MS   : Maximum Score reached at a given Olympiad
